foxbrew:
yea, i agree ... which i'm slowly realizing may be the source of my watered down brews ... i've had to call my last 3 batches "light" beers ...

looking into adjusting the false bottom i picked up for my MegaPot from Northern Brewer ... dropping it down at least an inch

hopefully that does the trick ..

tschmidlin:
It really depends on what you mean by dead space.  If by dead space, you mean space under the false bottom, then it is not a big deal.  If by dead space you mean volume that is not drained from the mash tun, then 11 quarts is a big deal.  Dropping your false bottom won't help with that though, which is why I think you mean the first version.  If it is a problem of not draining, adjust the pickup tube so that is reduced.  If it is extra water under the false bottom, drop the false bottom if it is easy, if not no big deal.  It's a lot, but it's not the worst thing in the world.

I have the screen tube which I got from the LHBS.  This effectively makes the deadspace in my mash tun less than two cups of coffee.  Virtually everything drains.  No issues with clogging either. 

What advantage does the false bottom offer that I'm missing?

False bottom can be an advantage if you fly sparge.  The false bottom having holes across the entire surface is thought to lessen channeling.  For batch spargers, there's no real advantage.

Good answer.  I will keep that in mind when I eventually switch to fly sparging.  I'd need a different setup than I have now tho. 

OP: Couldn't you devise something with less dead space?
